DM-100 is an emulsifier possessing
a much wider range of antibacterial spectrum than DP-95RF. Additionally,
compared with the middle chain length monoglycerides used up until this
time as an antibacterial agent, this gives a only a very subtle, uncomfortable
taste.
Therefore, we expect it to be used in various applications.

This table shows the antibacterial effect of DM-100, a test displaying
an effective inhibitory concentration by medium.
DM-100 inhibits the growth of gram-positive bacteria, but doesn't have
the antibacterial effect on gram-negative bacteria.

This table shows DM-100 compared with middle chain length monoglycerides
on the antibacterial effect.
M-100 is glycerine monocaprylate, M-200 is glycerine monocaprate, and M-300
is glycerine monolaurat.
DM-100 is more effective on gram-positive bacteria than middle chain length
monoglycerides. DM-100 has little effect on gram-negative bacteria
But if DM-100 is used together with middle chain length monoglycerides,
it will be more effective in various bacteria. |
